4. Application Notes
Typical application diagram
BRCS01V version EV charging controller
Vcc Pin (Power supply pin): The power supply voltage range to the sensor is 4.85 - 5.15 VDC, and the power ripple is not higher than 150mV. Ferrite beads and filter capacitors are suggested to be placed close to the Vcc pin. In addition, a LDO - such as LP2985A-50DBV- is strongly recommended to be used at the charging controller side.
Trip Pins (Fault signal output pin): When residual current in the circuit exceeds the threshold, the output level changes from low to high. Suggest adding ferrite beads and filter capacitors close to this pin. A direct connection of Pin 2/4 to switching devices- such as relays or contactors- is NOT allowed. The trip signal of Pin 2/4 is suggested to be monitored by the charging controller MCU.
TEST Pin (Self-test input pin): Before starting every charging, this pin is used to perform a simulated test to verify whether the sensor functions correctly.
Self-test Time Chart
A self-test excluding offset calibration is activated if Pin 5 - Test is connected to GND for a period of 40ms to 130ms; A self-test including offset calibration is activated if Pin 5 - Test is connected to GND for a period of 150ms to 1000ms. t1 is the response time for internally generated test current.
Offset Calibration Time Chart
An explicit offset calibration excluding self-test cycle is activated if Pin 5 - Test is connected to GND for a period of 2s to 3s. An offset calibration can be activated at regular intervals (such as start-up) or after the occur of certain critical events (such as short circuit).
Switching recovery level
If the trip-level is accomplished the output will change their state from low-level to high level. Depending on the existence of the residual current , the output will remain in this state until falls below the threshold
AC&DC Trip Pin: Typical values of DC 5mA & AC 24mA; Typical value of is 75%.
DC Trip Pin: Typical values of DC 5mA; Typical value of is 75%.

7. Additional Notes
Do NOT allow strong static electricity near the sensor, because static electricity can cause damage to the ICs inside the sensor. Take static electricity precautions when handling.
Do NOT exceed 260°C for 10 seconds when soldering the sensors. This is the maximum heat resistance grade of these sensors.
Do NOT drop the sensor or apply any other mechanical stress to the sensor, as such stresses may change performance characteristics.
Please place the sensor with an appropriate distance from components that can generate high magnetic fields, such as relays or contactors, to ensure accurate residual current detection.
Please refer to the product standards of RCD/RDC-DD (Residual Current Device / Residual Direct Current Detection Device), when designing built-in RCD/RDC-DD for mode-2/3 Electric Vehicle Supply Equipment with the sensor.
